High-performance aluminum cylinder kit from Airsal with 49.2cc displacement and hard-coated cylinder bore.

Aluminum cylinders dissipate heat much better than cast iron cylinders. The cylinders are therefore less susceptible to piston sticking or other temperature-related damage. The Airsal sports cylinder is already very powerful and offers a good torque curve. The compression ratio is designed for use with the original cylinder head. When fitting, the carburetor must be retuned or, better still, replaced with a larger sports carburetor.

All parts required for assembly are supplied as shown.

The manifold connection has an angled flange.
